Abstract
The invention relates to an energy storage device including at least one block having n energy storage units, where n≥2; a charge and discharge management circuit electrically linked to the n storage units and making it possible to alternately connect all of the energy storage units of one and the same block to one another; and the block having a defined block voltage between the low potential of the first energy storage unit and the high potential of the nth energy storage unit. The charge and discharge management circuit includes: first means for triggering the toggling from a parallel mode to a series mode and second means for triggering the toggling from the series mode to the parallel mode.
